Section Three: Assembling the Metal Detector Circuit. When it comes to making a metal detector, assembling the circuit is a crucial step. The circuit is the heart of the metal detector and is responsible for detecting metal objects. To start, you will need a few basic components such as a coil, a capacitor, a resistor, and an operational amplifier.

The metal detector consists of two parts, the detection coil and the filter circuit. The detection coil is the core part. After the coil is energized, a magnetic field will be generated, and if metal enters the magnetic field, it will cause the magnetic field to change, thus judging that there are metal impurities.

A sampling circuit in the metal detector is set to monitor the length of the reflected pulse. By comparing it to the expected length, the circuit can determine if another magnetic field has caused the reflected pulse to take longer to decay. If the decay of the reflected pulse takes more than a few microseconds longer than normal, there is ...
